There is a card on the floor near the spacecraft, it has a shine, just in front of the ammunition box, it may like everything has a bloom it is difficult to differentiate it
Just finished the game and made a long play of it. I gotta say I got jump scared two times with the "Boss fight" haha. First when I got the battery, the second time when I go to the hangar trying to escape. But all in all, I enjoyed the game, waiting for the second part of the game where IK go to the tower.
